The new merchant cargo ships use a large variety of steels in their construction; the steels range in yield strength from 40 to 100 ksi. Some of these steels require a close control of the welding procedure as well as other special techniques, to assure serviceability, and a special repair welding procedure must be developed, applicable for all strengths of steel used in construction and requiring a minimum amount of procedure control. The recommended temporary welding repair procedure and a discussion of the survey which led to the recommendation are described in this report.
